IMPROVEMENT INEYELETING-NIACHINES.

Speciieation forming part of Letters Patent N o. 126,916, dated May 21,1872.

To allpersons to whom these presents may come Be it known that I, JOHNE. WIGGIN, of Stoneham, of the county of Middlesex and State ofMassachusetts, have invented a new and useful or ImprovedEyeleting-llla'chine; and do hereby declare the same to be fullydescribed in the following specilication and represented in theaccompanying drawing, of which- Figure l denotes a top View, Figs. 2 and3 opposite side elevations, Figs. 4 and 5 opposite end views,Fig. 6 alongitudinal and vertical section of it.

Such other figures as may be necessary to a proper illustration oftheinvention are hereinafter referred to and described.

The machine punches the eyelet-holes, feeds along the material to beeyeleted, and inserts in each hole ind upsets an eyelet, the feeding ofthe material being effected by the anvil and its operative mechanism, inmanner as hereinafter described. The machine is so constructed thatafter each hole has been punched the anvil and punch are simultaneouslymoved backward laterally until the anvil is brought directly over thehole, after which' the anvil :is depressed intol the hole, and next ismoved forward laterally, so as to move forward the material the distancethat may be required for such hole to receive an eyelet, which is nextinserted in the hole and upset by the upsetter.

In the drawing the feeding-anvil is shown at ct, the punch at b, thepunch-bed at o, the work-supporting platform at d, the adjustable gaugeat e, the presser at f, the feedingspout at g, the eyelet-compresser ath, and the eyeall being arranged as shown.

Fig. 7 is a vertical section of the punch b, the bed c, and theircarriers, which consist of two arms, k l, formed and arranged as shownand hinged together at their rear ends. Fig. 8 is a top view of thework-supporting platform d and the adjustable gauge c and the presserf.

The main frame for sustaining the principal operative parts is shown atA, it having arranged in it and duly sustained in proper bearings adriving-shaft, B, provided with three grooved cams, D E F, and anadditional cam, G, side views of which are given in Figs. 9, 10, 11, and12. The feeding-anvil or upsetter projects from one arm of a lever, H,pivoted` to the head m of a vertical shaft, l, arranged in the mainframe, as shown, so as to be capable of turning horizontally, the leveralso turning vertically, as occasion may require. The bed-carrierl isfastened to the head m, and is movable therewith, the fastenings beingsuch as to admit of the bed and punch being adjusted to their properdistances from the anvil. The tail of the lever H is extended throughthe slot n of a guide, K, arranged and provided with an adjustable stopor screw, o, as shown. A spring, p, for moving thc lever back is appliedto the lever and an arm, q, of the frame. A lever, r, provided with africf tion-Wheel or stud to enter the groove of the camV F is pivoted tothe frame, and has its upper arm resting against the tail of the leverH. The purpose of the cam F and lever r is to move the lever H in adirection to cause the anvil or upsetter to feed along the cloth ormaterial to be eyeleted. The mechanism for depressing the punch-carrierconsists of the cam D, a lever, s, and connection-rods t u, arranged asrepresented,-there being to the lever a friction-roller or stud to enterthe groove of the cam. The presser f is xed upon a vertical slide-rod,t', provided with a depressing-spring, u. The said rod rests on a lever,o, which bears upon the cam G, all being arranged as shown. Theeyelet-com presser h is supported by a carrier, L, arranged to slidevertically between parallel guides M M, disposed as represented, thevertical motions of the carrier being effected by a cranked wheel, N, astud, and a slide, y, the slide turning on the stud and being disposedin a slot, z, made horizontally in the upsetter-carrier. The crankedwheel is fixed upon the outer end of the driving-shaft. In theeyeletcompresser and its carrier is the eyelet-receiver i, formed asshown, and supported upon a spring, a', arranged in the said carrier.The feedingspout g, disposed as represented, is supported by a standard,b', erected upon a slide, c, such slide being arranged between andsupported by parallel and horizontal guides,

d d', projecting from the frame, all as repre sented. A rocker-shaft,e', disposed under the slide transversely of the machine and in aysuitable bearing or bearings,carries an arm,

f', to extend from it between two projections,

lg h', ol the slide. Another arm, i', from the roclrereshat't is pivotedor jointed to the anvilcarrier, which, during its vertical motions,imparts, by means of the arm i', a reciprocating rotary motion to therocker-shaft, in consequence of which the feeding-spout will be movedtoward and away from the anvil, as occasion may require. Therocker-shaft is provided with an extra arm, It', whose otliee is toactuate a suitable mechanism for agitat ing a box or reservoir to causeeyelets to be delivered therefrom into the feeding-spout as in othereyeleting-machines. A pieceof leather or work to be eyeleted is to beplaced on the platform and between such and the presser and against theedge gauge. This having been done and the machine set in operation, thepunch will be driven downward, so as to punch a hole in the work, afterwhich the punch will rise out of the material, and, with the anvil orupsetter, will be simultaneously moved back laterally until the anvilmay be brought directly over the hole made by the punch. Next, the anvilwill be caused to descend so as to cause its finger l to enter the saidhole. Next, the presser will be raised offthe material in order to allowsuch materia-l to be ni o ved on the platform by the anvil or the ngermakin g part of such anvil. y Next, the punch b, the bed c, and theanvil a are to be simultaneously moved forward laterally, whereby thefinger will feed the material along until the ringer may come directlyover the eyeletreceiver t'. An eyelet being previously deposited on thereceiver, so as to encompass such and reston the compresser, the latterwill next be driven upward, and the presser will be drawnl downward, thewhole being so as to cause the material to be held firmly in place uponthe platform, the eyelet to be forced up into the hole of the materialand to be pressed against the anvil, so as to be inserted in thematerial and be lixed thereto by being upset in a manner wellunderstood.

l/Vhat I claim as my invention or improvement in eyeleting-machines isl. The punch b, its bed c, and the upsettinganvil e, arranged, as setforth, to have a lateral reciprocating motion, and provided withmechanism, substantially as described, for operating them as specified,so as to cause the material to be punched and fed forward, in order tobe eyeleted, by means essentially as explained.

2. And in combination therewith and the work-supporting platform, Iclaim the presser f, provided with mechanism for actuating it,

as described.
